Amodel airplane will be an exact copy of the original, but at 1/50 the size. the original airplane is 230 feet long. how many feet long should the model be? step 1: write a proportion that represents the problem. let x=length (in feet) of the model airplane. step 2: solve the equation you wrote in step 1. show your work.

A suitable proportion would be:

1 x

=

50 230 ft

Cross-multiplying, 230 ft = 50 x. Then x = 4.6 ft. That's a big model, but still this answer is reasonable.
